The satellite network does not have the IP layer where the IPsec [2][3] is designed for. Therefore, a new algorithm is needed to secure the satellite link at link layer or physical layer. This paper will give a short analysis on the advantages and disadvantages of the MPEG-2 TS encryption and present an approach trying to use the extension header of Unidirectional Lightweight Encapsulation (ULE...

Encapsulation is proposed as a safer way of handling energetic materials. Different encapsulation methods for explosives, such solvent evaporation, spray coating and supercritical carbon dioxide assisted encapsulation, were explored. Explosive training aids, where materials, triacetone triperoxide (TATP), erythritol tetranitrate (ETN) trinitrotoluene (TNT), are encapsulated in polymer matrix de...

In view of treating intracellular Brucella infections, microspheres made of poly(lactide) (PLA) and poly(lactide-co-glycolide) (PLGA) were developed as delivery system for the cationic and highly hydrophilic antibiotic gentamicin sulphate. Drug microencapsulation by spray drying yielded microspheres with regular morphology, an average particle size of approximately 3 micrometer and encapsulatio...

Interactions of the parasitoids Palmistichus elaeisis Delvare & LaSalle and Trichospilus diatraeae Cherian & Margabandhu (Hymenoptera: Eulophidae) with its alternative host Anticarsia gemmatalis (Hübner) (Lepidoptera: Noctuidae) affect the success or failure of the mass production of these parasitoids for use in integrated pest management programs. The aim of this study was to evaluate changes ...

Hepatocellular carcinoma is a common cancer in Asia with a poor prognosis. Tumour encapsulation has been shown to be a good, independent prognostic factor. The main cell in the liver responsible for extracellular matrix formation is the hepatic stellate cell, and this was investigated as the cell type responsible for encapsulation. This lecture discusses the role of hepatic stellate cells in he...

Natural polyphenols are valuable compounds possessing scavenging properties towards radical oxygen species, and complexing properties towards proteins. These abilities make polyphenols interesting for the treatment of various diseases like inflammation or cancer, but also for anti-ageing purposes in cosmetic formulations, or for nutraceutical applications. Unfortunately, these properties are al...

We report the first example of reversible encapsulation of micron-sized particles by oppositely charged submicron smaller colloids. The reversibility of this encapsulation process is regulated by pH-responsive poly(acrylic acid) (PAA) present in solution. The competitive adsorption between the small colloids and the poly(acrylic acid) on the surface of the large colloids plays a key role in the...

Recombinant human insulin was encapsulated within alginate microspheres by the emulsification/internal gelation technique with the objective of preserving protein stability during encapsulation procedure. The influence of process and formulation parameters was evaluated on the morphology and encapsulation efficiency of insulin. The in vitro release of insulin from microspheres was studied under...

In this work, we propose and develop the inorganic salt encapsulation of semiconductor nanocrystal (NC) dispersion in a nonpolar phase to make a highly stable and highly efficient colour converting powder for colour enrichment in light-emitting diode backlighting. Here the wrapping of the as-synthesized green-emitting CdSe/CdZnSeS/ZnS nanocrystals into a salt matrix without ligand exchange is u...
